Examination  Oral Examination Continuous assessment by workplace/daily
diary/report. Conducted through 1 Semester and 1 term. 
Learning Objectives
 To ensure that the student has a wide knowledge of
engineering and of work organisation, as well as to demonstrate how available
techniques, both practical and analytical, can be best applied.
 To gain a sound appreciation and understanding of the
theoretical principles learnt as an undergraduate through practical experience.
 To develop the skills, knowledge and attitudes needed to make
an effective start as a member of the engineering profession.
Learning Outcomes
 Gain a talent and attitude to fully enjoy a career in engineering
while recognising his/her responsibilities as a professional engineer in the
future.
 Be well equipped to undertake engineering projects, appreciating the
technical, safety, economic, commercial and social factors involved.
Outline Syllabus
There are a number of elements of training which should be
covered.

Induction
This is a short period to help the student in
the transition from academic to industrial life. The student should meet his/her
Mentor to discuss the content and objectives of the training. He/She should also
receive information on the organisation which he/she has joined, its products or
services and the terms and conditions of employment.
 Practical Skills
During this period the student should
receive instruction in the practical skills essential to his/her future
employment. It should also include an appreciation of the work of others in
converting an engineer's design into a final product, if appropriate.
 General engineering training
In a large organisation,
this should include an introduction to the work done in a number of departments.
Under these circumstances, he/she may eventually be working as one of a team and
therefore a good understanding of how others will work for and with him/her is
necessary.
 Directed objective training
The major part of his/her
training should have a direct application to the activity which he/she intends
to follow after he/she has been trained. At this stage he/she should be working
on real projects and be given increasing responsibility for his/her own work, to
stimulate his/her interest and establish his/her confidence.
Most of the training time will cover Design and Development,
Documentation and Data Preparation, Application or System Engineering and
Installation, Commissioning, Operation and Maintenance, Manufacture and Testing,
and Marketing and Sales.
[The method of training may vary from place to place as the
variety of occupations in Electrical Engineering is wide and continually
changing. ]

Outline Syllabus
The course will take the form of one or more field visits to
places of interest to electrical engineering graduates, such as power stations,
switchyards, electrical installations, electrical manufacturing plants,
renewable energy plants and micro hydro plants. Students will be required to
make a more detailed study of the major components than at Level 3.
The visits will usually be of two or 3 day duration.
The student will be assessed through an assignment to be
submitted on the observations and experiences gained during the visit. Oral
examination of the content of the report may also be used in the evaluation
